my right hand..... it almost detatches anyway.... always felt it would be fun to disconnect it and send it on random missions

Oh my gosh, isn't that in a movie?? Like, the addams family or something?

In the addams fmaily they do have a hand, also in Idle Hands the guys gets a demonic hand and chops it off. Then it runs around and kills people.

And in Evil Dead II( :Dead By Dawn, don'tcha know) Ash's hand is posessed and startsattacking him, so he cuts it off and replaces it with a chainsaw (the samesaw, in fact, that he used to cut it off...)

My torso. Defying physics as well as biology, while evoking maximum emotional response would be my goal. Yoshi already got head, so I'll have to go with something more over the top. Yes, I would like to be able to snatch my torso right out of its arms and legs configuration, using my teeth in a defiant growl, whipping it at my target like a dog flinging a rabbit to the ground. The regrowth process would start at the severed shoulder of my right arm, and it would sound like churning guts.

wow these are all really great chosen detachable body parts, made me lol.

i would have a detachable .... so hard to choose .... umm, face. so i could like rip it off, and then we could play a game with people wearing a face of mine and someone had to guess who was the real me. (face meaning eyes, lips, nose, all skin below hairline/ joining chin included)

boob definitely. probably left boob. watching unsuspecting people get hit in the face by a flying breast would never get old. tongue would also be hilarious, plus you could send it off to scavenge for food.
